SPECIFICATION forming part of Letters Patent No. 486,753, dated November22, 1892.

Application led July 13, 1892. Serial No. 439,927. (No model.) l

To all whom vt may concern:

Be it known that I, ELI E. BOOMHOWER, a citizen of the United States,residing at Morrisville, in the county of Lamoille and State of Vermont,have invented certain new and useful Improvements in Trusses; and I dodeclare the following to bea full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention consists in a new and improved truss, in which are embodiedseveral valuable and highly important novel features; and my inventionwill be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective viewillustrating my truss. Fig. 2 is a sectional View of the same.

' Fig. 3 is a perspective detail view on an enlarged scale.

The same numerals of reference indicate corresponding parts in all thefigures.

Referringto the several parts by their designating-numerals, 1 indicatesthe belt used in my truss, which buckles around the body of the wearer.To this belt, at the point indicated, a thin slightly-curved metal plate2, which may be made of steel or brass, is securely riveted, the platewhich carries the lever and pad being secured to this main plate 2, ashereinafter described.

The lever and pad carrying plate 3 is formed of metal in two parts, theshort upper section 4 and the longer lower section 5, the two partsbeing hinged together, as shown. rhe upper section 4 of the plate issecured to the main plate and belt by a central rivet 6, which serves asa pivot on which the plate may turn for the purpose of side adjustment,as hereinafter specified. The lower end of the plate-section 5 is formedwith a longitudinal slot 7, and the pad 8 is secured on the inner sideof this end, adj ustably, by means of a screw 9 passing through the slotinto the center of the pad, so that by loosening the screw the pad maybe moved up and down to adjust its distance from the belt.

To exert a perfect pressure on the pad,

which can be adjusted and regulated with the utmost accuracy, I employ alever, this small lever 10 being formed of metal and centrally pivotedin a bearing 11 on the outer side of the hinged plate 5, as shown, sothat its lower end (the lever being curved, as shown, preferably,although it may be made perfectly straight) will come in contact withthe head of the screw in the center of the pad, and the central part ofthe lever is formed with a series of apertures 12, through which itsremovable pivot pin passes, so that the lever can be adjusted in itsbearing when the pad is adjusted, and so that its lower end will alwayscome in contact with. the center of the pad. The upper end of the leveris formed with a threaded aperture 13, through which works anadjustingscrew 14, the endv or point of which bears on the upper plate4, preferably turning in a recess 6, formed in the end of the pivot 6.The upper end of the pivoted plate 4 is formed with a curved slot 15,through which a setscrew 16 passes into the main plate, and it will beseen that by this construction when the screw 16 is loosened the pad canbe adjusted to either the right or left, turning the plates 4 5 on thepivot 6.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, manner of adjustment andoperation, and decided advantages of my truss will be readily perceived.It will be seen that by the use of the pivoted lever and screw powerthat I obtain a means for holding the pad pressed to its place in usewith a constant and perfect pressure, which it is utterly impossible toobtain by the use of cams, &c. The pad and lever, as before stated, canbe adjusted to it the exact spot desired, and the pad can be further adjusted to the right or` left, as described. I do not conne myself to thescrew for operating the pivoted lever, as other equivalent means couldbe employed for moving the upper end of the lever in and out withoutdeparting from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a truss, the combination of a plate IOO centrally pivoted in abearing on the lower hinged' plate with its lower end extending over thecenter of the pad and having an adjusting-screw working through itsupper end against a fixed bearing on the belt, substantially as setforth.

In testimony whereof I affix mysignature in presence of two witnesses. v
